Moreover, a specific focus on low-frequency SSNHL should be set to better assess the possibility of an endolymphatic hydrops
in such cases.

While endolymphatic hydrops
is still thought to be the cause of Meniere disease, this theory has been challenged and migraine has been implicated as a common etiology between vestibular migraine and Meniere disease.

The pathophysiology of Meniere's disease is unknown, although dilation of the membranous labyrinth (i.e., endolymphatic hydrops
) is a closely associated finding on post-mortem studies  and, increasingly, on in vivo imaging as well [10, 11].
